HYDROCARBON-FURNACE.

SPECIFICATION forming part of Letters Patent No. 392,285, dated November 6, 1888.

(No model.)

To aZZ whom it may concern:

Beit known that I, JEFFERSON PATTEN, of Brooklyn, (Green Point,) county of Kings, and State ofN ew York, have invented a certain new and useful Improvement on Hydrocarbon-Furnaces, of which the following isa specification.

I will describe my improvement in detail and then point out the novel features in the claims. ,In the accompanying drawings, Figure 1 is a plan view, partly in section, of a hydrocarbon furnace embodying my improvement, taken on the plane of the dotted line a: x, Fig. 2. Fig. 2 is a vertical section ofthe same and showing parts of the steam-boiler broken away to save space, said figure being taken on the plane of the dotted line y y, Fig. l. Fig. 3 is a front view of parts of the same.

Similar` letters of reference designate corresponding parts in all the iigures.

A designates a combustion chamber. It may be made of metal, preferably of iron. lts upwardly-extending end a is shown as bellshaped and is open at the top. Below the bell-shaped portion the combustionchamber extends in an approximately horizontal direction toward the front of the'fnrnace, and is, as shown, cylindrical, or approximately so, upon its interior. This cylindrical portion has formed in it and extending about it upon its exterior an annular airpassage, B. This airpassage communicates with the external atmosphere. I haveshown openings (marked b) for this purpose which open upon the outside of the furnace. The annular air-passage com municates, as here shown, at the lower side of the combustion-chamber with a vertically-arranged air-pipe, C,which is also centrally'arranged in the upwardly-extending portion a.

The combustion-chamber is supported at its rear end, as shown, upon a leg, c', bolted or otherwise secured to any suitable support, and at its front side upon a plate, c2, also supported on a suitable support.

D designates the front of the furnace. Itis supported, as shown, on the plate c3. lExtending inwardly from this plate is a ring, 0*, which ring surrounds a portion of the combustionchamber,which includes the annular air-passage. Another ring, c5, extends inwardly from the plate D Within the combustion-chamber. Between the rings c ci and the combustionchamber any suitable packing may be interposed to form a rust-joint.

E E designate a combined inlet for hydrocarbon oil and a gas-retort. As shown, kthis inlet and gasretort are made of a single piece of pipe. The oil-pipe extends, as shown, to and around the air-ilue C, during which it is subjected to the action of heat in the combustion-c1iamber in a manner to be presently deseribed,whereby the oil becomes vaporized and returns through the vaporizing-retort E', as shown, to the exterior of the furnace.

Secured to the outwardlyextending end of the vaporiZing-retort is a U-shaped pipe, E. This pipe is shown as gradually lessening in diameter from its point of connection with the retort E to its point of connection with a short pipe, E*,which in effect constitutes a continuation of the pipe E. The pipe E" returns into the furnace through a suitable opening in the plate D. By reducing the diameter ofthe pipe c in the manner shown the vaporized oil or gaseous product is caused to flow through the pipe E* under considerable compressure and therefore with increased force.

I have shown the aperture in the plate D, through which the pipe E4 extends, as somewhat larger in diameter than the pipe E, whereby an annular passage is formed around the pipe E4, through which atmospheric air will be admitted to the interior of the combustion chamber, and will mix with the vapor issuing from the pipe E4, in order to facilitateA combustion.

Gr designates a pipe, preferably of slight diameter, which communicates near its outer end with a supply-pipe for oil,E2. This pipe extends into the interior of the combustionchamber through a suitable aperture in the plate D, and is employed for the purpose of supplying a small stream of oil to be ignited beneath the vaporizing-retort E and oil-pipe E, in order to begin the operation of the furnace. This stream of oil,when ignited, causes It will then be ignited bythe iiame ascending from the pipe G, andthe operation ofthe furnace is then established.

I have shown a cock, c, in the pipe G,where by oil maybe prevented from liowing through said pipe when the furnace is in operation.

In starting the operation ol" the furnace, oil issupplied to t-he oil-inlct pipe E from the pipe E2, receiving a supply ofoil from any suitable receptacle, maintained preferably in an cievated' position, so that oil will iiow into the oil-pipe by means of gravity.

I desire to mix steam with the oil ilowing through the oilpipe E, and for this purpose, after the operation oi' the furnace has conimenced, as described, I shut off the flow of oil from the cil-supply pipe Ef by means ofthe cock It. A stcanrinjector, J, (illustrated more clearly in Fig. 2,) and which may be of the usual orany ordinary constructiomis employed to cause a ilow of oil from a pipe, J, communicating with an oil-tank (not shown) by creating a partial vacuum inthe pipe J', in a wellknown manner. The ignited vapor passes upwardly into the bell-shaped upper portion of the Acombnstion-chainber, where it becomes mixed with'jeis of air flowing through horir/iontally-arrangedaperturesf in the upper end ofthe air-flue C. This mingling of the air and the gaseous ilame causes an intense heat and very perfect combustion.

I have shown my improved furnace as applied to a vcrtically-arranged steam-boiler, H, which niay he of the usual orauy ordinary construction; but the same may be applied to the heating of any other apparatus, if desirable.

lt may be seen that this furnace is very simple in construction, cheap, and durable, and that it has no parts which areliable to get out of order, while it may readily be taken apart to repair or replace the oil-pipe and va por-retort, if desirable.

\Vl1at I claim as lny invention, and desire to secure by Letters Patent, is-

1. In a hydrocarbon-furnace, the combination, with a combustion-chamber having a horizontally-extending portion, and an upwardly-extending portion having an open upper end, of an air-pipe extending vertically and centrally through the up wardly-extendi ng portion of said combustion chamber, and provided ncar its upper end with horizontallyextendingapertures, an air-passage with which said air-pipe communicates, and an oil-pipe and valjiorizing-pipe extending into said combustion-chamber and subjected to the influence of the products of combustion, substantially as speciiied.

2. In a hydrocarbon-furnace, the combination, with a horizontal combustionchamber having a vertically-arranged portion open at its upper end, of an air-pipe arranged vertically and centrally in said vertically-extending portion and provided with horizontally-extending apertures in its upper end, an oilpipe extending from the exterior of said conibustion-chainber into the same, and a vaporizing-retort communicating with said oil-pipe and extending to the exterior of the combustion-chamber, the vaporiZing-retort being coilnected at its outer end with a pipe of gradually-lessening diameter returning tothe interior of the combustionchamber, substan tially as specified.

3. In a hydrocarbon-furnace, the combination, with a horizontal combustiori-chamber provided with an upwardly-extending portion having an open upper end of an air-pipe arranged vertically and centrally in said upwardly-extending portion and provided with horizontally-extending apertures near its upper end, of an annular air-passage formed in the wall of said horizontal coinbustion-cham ber and communicating with said verticallyextending air-pipe, said annular air-passage having openings communicating with the eX- ternal atmosphere, and an oil pipe and a gasretort extending into the combustion chamber, substantially as specified.
